Orthodontic appliances for children, interceptive braces and orthodontic brackets for adolescents.
The first consultation, recommended around the age of 5, 6 or 7, will determine whether or not the child needs orthodontic treatment, for example if he or she has a misalignment of the jaws or a lack of symmetry. If the upper teeth are very advanced, if the lower jaw does not perfectly match the upper jaw, or if there is a mismatch between the upper and lower teeth, braces are necessary.
If the child’s jaw development is not sufficient to allow for a lack of space, it is important to act at the right time in relation to the growth to prevent the situation from getting worse.
Treatment by invisible transparent aligners : / aligners / orthodontics for adults / invisalign : the advantages of invisalign :

Invisible, aesthetic
The first advantage of the transparent aligners / invisible smilers is its discretion. Indeed, the use of removable gutters in thermoplastic makes them almost invisible, because transparent. The aesthetic result is therefore much better than that of braces. This discretion allows adults in particular to take the plunge more easily, something they would not have done in the past for fear that the unsightliness of braces would interfere too much in their daily lives. The treatment is very aesthetic, not very embarrassing, and will perfectly correct your teeth that are crooked, in order to regain a good occlusion, find a smile that you like, a proper chewing, and limit the neck pain and headaches that can come from a dental malocclusion.
Removable
The invisible orthodontic device for adults with transparent aligners is completely removable. In fact, you can remove your aligners yourself to eat, drink, and maintain a good daily dental hygiene, but you will have to wear them almost all day to obtain the desired result. You will be able to eat and drink what you want because at mealtime you must remove the aligners. You won’t have to suffer from the dietary constraints associated with traditional braces. No stuck food, no injuries.
Comfortable, no pain, no injury
More comfort for patients. Thanks to its custom-made design, the clear aligners fit perfectly in the patient’s mouth and teeth for maximum comfort. There is no risk of irritation or injury because the aligners are made of thermoplastic (a flexible material), unlike traditional orthodontic appliances made of metal wires that are more rigid and injurious to the patient’s mouth.
